Oscillators are electronic circuits that generate periodic and regular waveforms at audio frequency. The CCHD-950-25-74.1758 is an oscillating circuit developed by Comany X which can generate waveforms with a frequency range of 35 kHz to 950 kHz. This device is mainly used for testing and conditioning of signal processes in both industrial and radiofrequency applications.

The CCHD-950-25-74.1758 has two main components, a frequency adjustable voltage controlled oscillator (or VCO), and a phase-locked loop (or PLL). The VCO is responsible for generating oscillating signals with a frequency that can be adjusted up or down depending on the input voltage. The PLL, on the other hand, feeds back the VCO output and synchronizes the output frequency to closely match the input signal frequency. This circuit further minimizes the frequency deviation of the output signal ensuring a stable operation.

The CCHD-950-25-74.1758 is typically used in applications where local oscillation is needed for signal conditioning and testing purposes. It is specifically useful when used to generate a high accuracy and stable sine wave with a frequency of up to 950 kHz. This device can also be used to isolate and attenuate high frequency signals while passing lower signals on to other circuits. It can be used in radio frequency tuning and squelch damping, FM demodulation, and data acquisition circuits to name a few.

The CCHD-950-25-74.1758 is also suitable for some motor control applications. Its wide frequency range and reasonable voltage levels make it an ideal choice for frequency to voltage conversion, Pulse width modulation and servo control systems. Because the output voltage remains stable, it can be used to control the speed of variable speed motors.

In terms of working principle, the CCHD-950-25-74.1758 uses two components, a VCO and a PLL, to adjust and maintain the frequency of the generated signal. The VCO is responsible for setting the frequency of the waveform while the PLL is responsible for ensuring that the output frequency matches the input frequency. The frequency adjustment is accomplished by varying the output voltage of the VCO, which is then compared to the input signal voltage. If the two voltage levels differ, the frequency of the VCO is adjusted until it matches the input signal.

The CCHD-950-25-74.1758 is a versatile and highly accurate oscillator capable of producing waveforms with a frequency range of 35 kHz up to 950 kHz. It is mainly used for testing and conditioning of signal processes in both industrial and radiofrequency applications. It can also be used to control motor speeds and be employed in range of other application such as frequency to voltage conversion and Pulse Width Modulation. This device is known for its stability and accuracy due to the use of the VCO and PLL components for frequency adjustment.
